BATTERY POWER METER. Provides continuous feedback on the condition of the batteries, indicating high, medium or low battery life. This information allows you to make educated decisions about changing batteries or packing a spare set.
DIMMABLE LED: Provide the precise output needed for a given task, and help conserve battery power for maximum efficiency. Sometimes we use the word dimmability, which isn't exactly a word yet, but we're very fond of it and have faith it will become one.
IPX7. Lights provide waterproof integrity down to 1 meter for up to 30 minutes.
LED OPTIC COLLIMETER. A collimator gathers all available light from an LED in the form of scattered rays and re-emits the light as parallel rays, making it more optically efficient than a standard reflector.
MAXBRIGHT LED. The highest quality LED available. Extremely bright and efficient. Emits a smooth, powerful, white light useful for a wide range of tasks. Princeton Tec uses collimators or reflectors with the Maxbright LED depending upon the application.
The brightest headlamp in our professional series, the Apex, has been a favorite of extreme outdoorsmen and cavers for years. The pinnacle of waterproof LED headlamp design, the Apex incorporates a single regulated Maxbright LED plus four regulated Ultrabright LEDs. The Apex is capable of a powerful spot beam or a bright flood, and two switches make changing modes intuitive. Proprietary heatsink technology allows the LEDs to burn brighter and longer.
